ISen-L201 Fiber Bragg Grating Vibration Sensor

The ISen-L201 is a fiber Bragg grating vibration or acceleration sensor. It is designed as a spring–pendulum system, with a metal beam serving as the spring and a fiber Bragg grating attached as the sensing element.

The ISen-L201 is designed to measure vibration or acceleration in harsh environments. Its optical operating principle makes it immune to electromagnetic interference and lightning. It measures dynamic signals, and long-distance sensing is a key advantage for many structural and geological monitoring applications.

The product comprises two sensing elements and is therefore sensitive in two directions. It can be adhesively bonded or bolted to the vibrating structure.

Technical Advantages

Ultra-High-Precision Multi-Parameter Measurement
Simultaneous output of triaxial acceleration, angular velocity, angle and temperature signals provides comprehensive condition sensing.

Ultra-Low Noise and Ultra-High Resolution
An ultra-low-noise design and exceptionally high signal resolution accurately capture weak vibration and small tilt changes.

Advanced Temperature Compensation Algorithm
A built-in high-speed microprocessor performs linear signal conditioning and temperature compensation, maintaining stable accuracy and extremely low drift across a wide temperature range.

Strong Electromagnetic Compatibility
Excellent EMC and interference immunity, with internally shielded signal ground isolated from the housing, ensure stable operation in complex electromagnetic environments.

High Protection Rating
A welded metal seal provides protection rated IP67 or higher, impact resistance and lightning protection for harsh industrial environments.
